NAME

       thumbnailer-service - Thumbnailer service

SYNOPSIS

       thumbnailer-service

DESCRIPTION

       The  thumbnailer-service  program  provides a DBus service for creating thumbnail images from local media
       files (photos, audio, and video files), as well as  album  cover  artwork  and  artist  images  for  many
       musicians and bands.

       Original  images  and  scaled thumbnails are cached on disk, so requests for a thumbnail for a previously
       retrieved image (whether in the same size or a different size) are delivered as efficiently as possible.

       The service is fast and scalable, and it guarantees the integrity of on-disk data structures even in  the
       face of a crash or power loss.

       The service is activated on demand by DBus and, by default, shuts down after 30 seconds of idle time.

       The  service  connects  to  the DBus session bus as com.canonical.Thumbnailer.  The interface to retrieve
       thumbnails is provided at the path /com/canonical/Thumbnailer,  and  the  administrative  interface  (see
       thumbnailer-admin(1)) is provided at the path /com/canonical/ThumbnailerAdmin.

CONFIGURATION

       The service uses dconf(7) for its configuration. See thumbnailer-settings(5) for details.

ENVIRONMENT

       The service reads the following environment variables:

       THUMBNAILER_UTIL_DIR
              The  directory  in which to look for the vs-thumb executable, which is used to extract images from
              streaming media. If not set, the program is expected to be in /usr/lib/<arch>/thumbnailer.

       THUMBNAILER_MAX_IDLE
              The service exits once it has been idle for the number of milliseconds specified by this variable.
              If not set, a default value of 30000 is assumed.

       THUMBNAILER_UBUNTU_SERVER_URL
              This  variable  overrides  the  URI  of  the  remote  image  server.  If  not set, the default URI
              https://dash.ubuntu.com is used.

       THUMBNAILER_LOG_LEVEL
              This variable overrides the value of the log-level setting.

       XDG_CACHE_HOME
              This variable determines the location of the on-disk caches. Caches are written to  subdirectories
              of $XDG_CACHE_HOME/unity-thumbnailer. If XDG_CACHE_HOME is not set, $HOME/.cache/unity-thumbnailer
              is used. If $HOME is also not set, the home directory is determined by its setting in  /etc/passwd
              and home-dir/.cache/unity-thumbnailer is used.
